Electric racing bodywork

Composite bodywork developed from vehicle packaging and surface CAD through CNC tooling and final layup

Year
2020-2023
Role
Lead bodywork engineer; team of 15+
Tools
SolidWorks, HSMWorks, CNC, fibreglass
CAD model of bodywork fitted to a student electric racecar
Body surface developed around the chassis, suspension and driver

Design

The shell had to clear the chassis, suspension and driver while remaining practical to manufacture. I led the team's SolidWorks surface development and split the design into machinable foam sections, so tooling constraints shaped the geometry from the start.

Tooling

I generated HSMWorks toolpaths and machined more than fifty foam sheets. I indexed and joined the sections, then filled and sanded them into a full-size mould; alignment and finishing determined the surface quality of the final part.

Composite shell

We laid fibreglass over the prepared mould, cured it and trimmed the shell to the chassis. The project connected team leadership and surface CAD with CAM, tooling, composite manufacture and final fit.
